Main aim of this master’s thesis is to identify, model and control robotic manipulator with three degrees of freedom. The thesis is a part of major project [17], the aim of which is to create an educational platform. In the thesis the simple PID control and the PID with feedforward compensation control is tested on the model of simple pendulum. In the next part models of DC motors, which are used for construction of the manipulator, are developed and the inverse dynamics model of manipulator is developed. This model is used for feedforward control of the manipulator. In the final part the application was developed, which allows the manipulator to be taught some movements, which can be later on, executed. For the simple control of the application the graphical user interface was programmed.

This diploma thesis has its purpose in creating such an editor of LATEX language, which would succeed in the competition of existing solutions. To offer users a basis typical for this type of editors and add functions that will make him a unique project. The progress went in a direction of transparent environment and completely trivial operating. Most of the functions are available through 1 click only. Predefined templates are displayed immediately including previews and it is possible to download them with all source codes. Some kinds of actions redraw the whole content of the page. In other cases, we used update panels for partially redraw the content or client javascript. Due to available archivation of .zip files we can even process more files at the same time. Program is designed in a way to be able to further continue developing it and even broaden his features.

Graphical user interfaces for high-assurance systems must fulfill a range of security requirements such as protected and reliable presentation, prevention of unauthorized cross-domain talk, and prevention of user-input eavesdropping. Additionally, it is desirable to support legacy applications running in confined compartments. Standard isolation methods such as virtual-machine monitors provide one frame buffer per security domain, where each frame buffer is managed by one legacy window system. This raises the question of how to safely integrate multiple (legacy) window systems and protect the displayed data while preserving the usability of modern user interfaces. Our paper describes the OverlayWindow System, a general mechanism for multiplexing windows of multiple distinct window systems into the host frame buffer. Thus, each legacy window appears to the user as one corresponding host window that can be moved and resized. To achieve this, only slight modifications of the legacy window system are required whereby, the source code does not have to be available. Our implementation of an Overlay Window System successfully multiplexes Linux, GEM and native L4 applications.

At the moment, there is no quick and easy method to measure muscle shaking (tremor) reliably. In order to avoid long waiting times for an Electromyography (EMG) investigation, this thesis aims to create an Android smartphone application capable of measuring muscle tremor at a moment’s notice. A previous attempt has been made showing promising results but no sign of follow-through has been found. This thesis project was specifically requested by researchers from the Center for Neurology at the Academic Specialist Center, whom have the resources to continue to develop the project given useful results. The results of this thesis project was a deliverable Android mobile application, developed using the programming language Kotlin in Google’s Integrated Development Environment (IDE) Android Studio. The application implements the software architectural design pattern Model View View-Model (MVVM) in order to make the code modular as well as easily maintainable in the future. In terms of User Interface, the application follows the familiar and popular design system by Google called Material Design, with the purpose of making the application intuitive and easy to use. The work process consisted mainly of iteratively collecting feedback from the project’s stakeholders. The results of the application’s tremor measurement were acquired by conducting a small patient trial, where the application’s frequency analysis was compared against a third-party application. Using an Electromyograph as the "true" answer, it was found that the application developed for this thesis gave results closer to the Electromyograph than the third-party application. To continue this research, the codebase for this project can be built upon to use external accelerometers to acquire measurements of several limbs at the same time. A further continuation could also be to encrypt the measurement data to increase privacy. / I nuläget finns det inget lättillgängligt och pålitligt sätt att mäta muskelskakning (tremor) på. Den här uppsatsen har som syfte att skapa en Androidapplikation för att lätt kunna mäta muskelskakningar. Förhoppningen är att patienter ska slippa långa väntetider inför deras explorativa EMG-utredning, i och med att läkare ska kunna använda mobilapplikationen direkt vid ett tidgit klinikbesök. Ett tidigare försök att skapa en sådan här app har gjorts men utan någon uppföljning. Detta examensarbete har skett på förfrågan av forskare hos Akademiskt specialistcentrum inom enheten "Centrum för neurologi". Resultatet av detta examensarbete var en Androidapplikation som har utvecklats med programmeringspråket Kotlin i den integrerade utvecklingsmiljön Android Studio. Applikationen använder sig av arkitekturmönstret Model View View-Model (MVVM) med syfte att modularisera koden så mycket som möjligt och att göra den lätt att underhålla i framtiden. När det kommer till användargränssnittet så använder sig applikationen av Googles designsystem Material Design", med tanken att användandet av populär och väligenkänd design gör appen mer användarvänlig. Då syftet med applikationen är att mäta muskelskakningar, har ett småskaligt patienttest genomförts där applikationens resultat jämförts med en elektromyograf samt en tredjepartsapplikation. Då elektromyografens resultat använts som facit, har resultaten visat att applikationen som utvecklats i samband med detta arbete gett ett bättre resultat än tredjepartsapplikationen. För att fortsätta på detta examensarbete, kan applikationen vidareutvecklas för att lägga till stöd för externa accelerometrar, med syfte att genomföra mätningar på flera extremiteter samtidigt. En ytterliggare fortsättning skulle kunna vara att kryptera mätdatan som applikationen genererar för att förbättra dataintegriteten.

Human-controlled robots are utilized in many situations and such use is becoming widespread. This thesis details research that allows a single human to interact with a team of robots performing tasks that require cooperation. The research provides insight into effective interaction design methods and appropriate interface techniques. The use of team-level autonomy is shown to decrease human workload while simultaneously improving individual robot efficiency and robot-team cooperation. An indoor human-robot interaction testbed was developed at the BYU MAGICC Lab to facilitate experimentation. The testbed consists of eight robots equipped with wireless modems, a field on which the robots move, an overhead camera and image processing software which tracks robot position and heading, a simulator which allows development and testing without hardware utilization and a graphical user interface which enables human control of either simulated or hardware robots. The image processing system was essential for effective robot hardware operation and is described in detail. The system produced accurate robot position and heading information 30 times per second for a maximum of 12 robots, was relatively insensitive to lighting conditions and was easily reconfigurable. The completed testbed was utilized to create a game for testing human-robot interaction schemes. The game required a human controlling three robots to find and tag three robot opponents in a maze. Finding an opponent could be accomplished by individual robots, but tagging an opponent required cooperation between at least two robots. The game was played by 11 subjects in five different autonomy modes ranging from limited robot autonomy to advanced individual autonomy with basic team-level autonomy. Participants were interrupted during the game by a secondary spatial reasoning task which prevented them from interacting with the robots for short periods of time. Robot performance during that interruption provided a measure of both individual and team neglect tolerance. Individual robot neglect tolerance and performance did not directly correspond to those quantities at the team level. The interaction mode with the highest levels of individual and team autonomy was most effective; it minimized game time and human workload and maximized team neglect tolerance.

Corporations have gathered data about their business and employees for as long as the concept of business has existed. With the digitalization of the world, the possibility of how much data is stored has exploded and today it can be hard for companies and especially managers to make sense of all stored data. Utilizing this data is something that has grown to be very popular but how to do it is not straightforward. The objective of the thesis was to discover what data is important for an organization and how that should be used and visualized in a digital environment. The design thinking framework was used to come up with the best possible design for a digital support tool for managers. The resulting prototype proposes a way of how trends and accomplishments among coworkers, a list of things the manager have to take action on, how the team has reported on projects, monthly reports for budgetary target, time to customer, working time, and profitability and lastly visualization of the following data over time; "pejling", "time to customer", "internal time", "hourly rate", "working time", "profitability", "absence", and "overtime" should be designed in a digital support tool. / Företag har samlat data om deras organisation och anställda så länge som kon- ceptet företag har funnits. Med digitaliseringen av världen har möjligheterna för hur mycket data som sparas exploderat och idag kan det vara svårt för före- tag och speciellt chefer att förstå all sparad data. Att utnyttja det här datat har växt till att bli väldigt populärt men hur man gör det är inte självklart. Målet med det här examensarbetet var att förstå vilket data som är viktigt för en organisation och hur det ska användas och visualiseras i en digital miljö. Design thinking ramverket användes för att ta fram den bästa möjliga designen för ett digitalt chefsstöd. Den resulterande prototypen visar ett sätt på hur trender och prestationer bland medarbetare, lista med saker en chef måste ta tag i, hur teamet har rapporterat på projekt, månadsrapporter för budgetmål, tid mot kund, arbetstid och lönsamhet, och slutligen visualisering av följande data över tid; "pejling", "tid mot kund", "interntid", "timpris", "arbetstid", "lönsamhet", "frånvaro" och "övertid" kan designas i ett digitalt chefsstöd.
